ClientHandlerException:找不到MIME媒体类型multipart/form-data

Question

我正在使用Jersey client来访问Spring MVC REST控制器，以实现图像上传功能。我得到了以下异常：

com.sun.jersey.api.client.ClientHandlerException: A message body writer for Java type, class org.springframework.web.multipart.commons.CommonsMultipartFile, and MIME media type, multipart/form-data, was not found

我发布图像的控制器方法：

@RequestMapping(value = "/file/upload", method = RequestMethod.POST)
public String fileUpload(@RequestParam("fileUpload") MultipartFile file, 
Model model, HttpServletRequest request, HttpServletResponse response)
{
try
{   
    ClientConfig config = new DefaultClientConfig();
    com.sun.jersey.api.client.Client client = com.sun.jersey.api.client.Client.create(config);
    WebResource webResource = client.resource("/save-image");

    ClientResponse responseMsg = webResource
            .type(MediaType.MULTIPART_FORM_DATA)
            .post(ClientResponse.class, file);          
}
catch (Exception e)
{
    logger.error("Exception in fileUpload()", e);
    return "error";
}
return "success";
}

我的REST控制器方法获取post数据：

@ResponseBody
@Consumes(MediaType.MULTIPART_FORM_DATA)
@RequestMapping(value = "/save-image", method = RequestMethod.POST)
public String saveImage(@FormDataParam("file") MultipartFile file, ModelMap 
model)
{
    //Code to save the image
}

有没有解决这个异常的办法。我已经尝试了以下堆栈解决方案，但我仍然得到相同的异常。
